Gas Fermentation at Calysta
Gas Fermentation is the Next Step in Industrial Biotech
22/10/2020 2
• Lower cost feedstocks are needed for biological products to compete with petroleum derivatives
• C1 feedstocks (CH4, CO, CO2) are accepted to be among the cheapest sources of carbon
• C1 feedstocks are generally pollutants, with significant safety and solubility issues compared to traditional biofeedstocks
• Calysta owns the world’s only commercially-validated gas fermentation technology allowing use of C1 feedstocks
Calysta’s Methanotroph Platform

Methylococcus capsulatus Bath
• Gammaproteobacteria, type I methanotroph• Relatively fast growth rate (methane:oxygen mix)• Genome sequence available• Amenable to genetic manipulation• Only methanotroph proven at commercial scale• Variety of formats for strain testing: well plates,
pressure bottles, 2L fermenters• Amended media and optimized feeding strategies
produce high cell densities in small scale.

Calysta has developed a set of novel engineering tools for methanotrophs:
• Reporter genes
• Plasmids that replicate both in methanotrophs and in E. coli
• Constitutive and inducible (low/med/high) promoters
• Techniques for chromosomal knockin and knockouts
Different promoter gene-fusions with synthetic fluorescent and chromogenic proteins (non-Aequorea) expressed in M. capsulatus

Calysta FeedKind Production Process
6
FeedKind Protein Commercial Samples Shipping Worldwide from Teesside UK Plant
• Production of ~50 tons/year
• Shipping commercial samples to customer and partners worldwide
• Facility is a “scale-down” of the original Tjeldbergodden, Norway reactor, demonstrated to produce at a rate of 10,000 mtpa
• Successful maintenance of 12+ weeks of continuous fermentation, exceeding design parameters for key commercial metrics such as yield and productivity
• Partnered with Center for Process Innovation (“CPI”) to provide on site services and well trained staff
Fermenter in Teesside, England.

FeedKind Protein is composed of naturally occurring
microorganisms that metabolize methane as their sole source
of carbon and energy, producing a nutritious, high-protein
biomass
✓ FeedKind is a non-GMO source of protein obtained by
natural fermentation
EU Register of Feed Ingredients, 2017
✓ Approved in the EU, Japan and Australia
✓ Can be used in Canada and in the Philippines
✓ On-going regulatory process in the USA
✓ Additional countries in process
FeedKind® is a Natural, Non-GMO Protein Source

Calysta Commands a Leading IP Position, Creating Significant Barriers-to-entry
• >50 granted patents with over 100 pending applications covering more than 22 patent families
• Strong claims covering proprietary reactor design that have already invalidated one potential competitor’s patent
• Broad claims granted in 2016 covering biological production of any chemical from natural gas
• Aggressively filing on new gas fermentation reactor designs and improvements with 4 new issued patents and 15 applications in the area
• 38 pending applications in the area of animal feed
